While you are waiting for getting help, here are some tips to improve your experience:

Code is much easier to read if posted with syntax highlighting and proper formatting.

If nobody is calling back, that usually means that your question was not well asked and hence nobody feels confident enough answering. Try to use your time to elaborate, provide details, context, more code, examples and maybe some screenshots. With enough info, someone knows the answer for sure.

Don't forget to close your thread using the command </help-thread close:1027500463647621170> when your question has been answered, thanks.

#

the first tree is correct but the second tree has an unexpected third line at the base

#

also is coding always this confusing with like spaces and math lol i feel like everything before this came pretty simple then bam this exercise

twin sage Mar 28, 2023, 6:38 AM

#

those exercises are to practice loops and get a better understanding of which part in ur loops controls what

rocky cove Mar 28, 2023, 6:38 AM

#

gotcha cause im pretty sure just getting confused with the math portion of it

#

something is just slightly off

twin sage Mar 28, 2023, 6:39 AM

#

yeah don't worry. it's all just practice. we all struggled with those things until we did it a few times

#

i didnt quite understand which part of the output is wrong. the output u shared only has two rows for the second tree base?

rocky cove Mar 28, 2023, 6:40 AM

#

well if i remove the = in for (int i = 0; i <= height / 4; i++) { it gives me the correct amount in the second tree and the wrong amount in the first tree

#

the output is supposed to look like this

For example, the call christmasTree(4) should print the following:

Sample output

   *

****

   *
  ***
 *****

The call christmasTree(10) should print:

#

so now ur missing a line in the base of the second tree?

rocky cove Mar 28, 2023, 6:42 AM

#

well i just added the = back

#

just not sure where im going wrong here

twin sage Mar 28, 2023, 6:43 AM

#

ah wait. i thought ur showing 3 trees, but its 2 trees

rocky cove Mar 28, 2023, 6:43 AM

#

sorry

this is the output im getting

can u show the task? maybe they want / 3 and not / 4 or other stuff?

rocky cove Mar 28, 2023, 6:44 AM

#

Define a method called christmasTree(int height) that prints the correct Christmas tree. The Christmas tree consists of a triangle with the specified height as well as the base. The base is two stars high and three stars wide, and is placed at the center of the triangle's bottom. The tree is to be constructed by using the methods printSpaces and printStars.

For example, the call christmasTree(4) should print the following:

Sample output

   *
  ***
 *****
*******

  ***
The call christmasTree(10) should print:

Sample output

twin sage Mar 28, 2023, 6:45 AM

#

it seems the base of always supposed to be 2 rows only

#

so u don't need any math

#

nothing based on height. just always 2

rocky cove Mar 28, 2023, 6:45 AM

#

yeah

twin sage Mar 28, 2023, 6:45 AM

#

so just create a loop that makes two rows. nothing dynamic

#

u kinda overcomplicated it

#

by making some math depending on the height

rocky cove Mar 28, 2023, 6:46 AM

#

so just take out the height / 4?

twin sage Mar 28, 2023, 6:46 AM

#

but literally just put 2 there instead

rocky cove Mar 28, 2023, 6:47 AM

#

got it!

#

i did this

#


public class AdvancedAstrology {

    //Creates a method to print stars
    public static void printStars(int number) {
        for (int i = 0; i < number; i++) {
            System.out.print("*");
        }
        System.out.println();
    }

    //Creates a method to print spaces
    public static void printSpaces(int number) {
        for (int i = 0; i < number; i++) {
            System.out.print(" ");
        }
    }

    //Creates a method to create a triangle
    public static void printTriangle(int size) {
        for (int i = 1; i <= size; i++) {
            int spaces = size - i;
            printSpaces(spaces);
            printStars(i);
        }
    }

    //Creates a method that makes a cristmas tree
    public static void christmasTree(int height) {
        for (int i = 0; i <= height; i++) {
            int spaces = height - i;
            printSpaces(spaces);
            if (i == 0) {
                System.out.println(" ");
            }
            printStars(2 * i - 1);
        }
        for (int i = 0; i <= 1; i++) {
            printSpaces(height - 2);
            printStars(3);
        }
    }

    //Main code
    public static void main(String[] args) {

        //Prints Triangle, Christmas tree and big tree
        printTriangle(4);
        System.out.println("---");
        christmasTree(4);
        System.out.println("---");
        christmasTree(10);
    }
}

twin sage Mar 28, 2023, 6:47 AM

#

works now? looks good

rocky cove Mar 28, 2023, 6:47 AM

#

oh wait

#

im still failing somehow

twin sage Mar 28, 2023, 6:48 AM

#

but one problem less cat_thumbs_up

rocky cove Mar 28, 2023, 6:48 AM

#

yeah lol

#

idk why its giving the expected output i think

twin sage Mar 28, 2023, 6:48 AM

#

maybe u have a trailing newline somewhere?

rocky cove Mar 28, 2023, 6:48 AM

#

When calling christmasTree(4) is called, the first line should contain 3 spaces and then one star, make sure there's not too much or too little spaces

twin sage Mar 28, 2023, 6:48 AM

#

like posting an empty line too much at the end

rocky cove Mar 28, 2023, 6:50 AM

#

fixed it

#

changed int i = 1 in the top part and it passed

#

damn that took me forever thank you for the guidence ❤️
